Community Division-Based SWoT Ontology Directory Service

On account of plenty services among Internet of Things (IoT) with a poor efficiency in semantic organization and dynamic management to various service resources, Semantic Web of Things (SWoT) is prompted as its improved form. To solve this problem, a method named as community division-based ontology directory service is proposed to organize domain-related services in SWoT, and a prototype system for community division-based SWoT ontology directory service named as CDB-SWoT-ODS is designed. In system CDB-SWoT-ODS, ontology summarization is used to reduce service ontology volume firstly, then unstructured P2P socialized network are resolved and divided into dynamic semantic communities through an autonomic community generating algorithm (SoFA), which get ready for generating ontology directory. Furthermore, a pattern tree cater to user preferences is generated and stored into ontology directory service module. As a result, by using SWoT ontology directory generating algorithm (SWoT-ODG), a service candidate set can be automatically pushed to service applicants, so that comprehensive and efficient users' personalized service needs can be satisfied.
